More natural gas vehicles in the future?

[SVOboy]

After hearing about demand being almost doubled for the Honda Civic GX, I was surprised to come across this bit of news on GCC:

Mercedes-Benz is putting its Sprinter 316 /516 NGT natural gas van into series production, with market launch targeted for May 2008. The company began showing prototypes of the Sprinter NGT at vehicle shows last year. (Earlier post.)

Although Daimler has offered a natural gas version of the Sprinter since 1997, this is the first time the company has built a compressed natural gas version of the Sprinter from first principles. In the past, the NGT Sprinters have used a conversion from a gasoline engine—the M 111 E 23.

The engine on the Sprinter NGT is also applied in Mercedes-Benz passenger cars. Mercedes-Benz uses a bivalent system—the basic engine, a four-cylinder unit with a displacement of 1.8 liters, will also run on gasoline, extending the range of the Sprinter up to 1,200 kilometers (746 miles).

I just spent 16 hours in one of these vans, just wish I had had the option of calculating the mileage for it, . Definitely good rides though.

I do hope so. There is a good market for them. Even with limited refueling stations. The Honda Civic GX has a home refueling station which helps.

I heard from someone "in the know" that NG is the big wave of the future too, but I am skeptical. Here in SoCal it is easy because we already have a decent NG infrastructure. But, I can't see that there is enough to go around. As one component in a multi-pronged solution, I could imagine this becoming maybe 5-10% of the cars being driven.

I like the bi-fuel option on the Benz. That's a good idea.

The Sprinter has been a great alternative to the Econoline and Full-Sized GM Vans (Express). I'm hoping the new (to the U.S., in 2010) Ford Transit Connect will be a hit too...

Good question. Since it involves considerably less refining, it should be cheaper. The savings really comes from the long-life and durability of the high-compression engines. This is an old study from 1999, but it shows NGVs to be ~25% more efficient. If you take the price of gasoline and Natural Gas from this examination, and extrapolate it to today's figures, it should remain constant.

I've wanted a Phill System and a GX for a while now. It would need to be an early 1.6L with a swapped manual gearbox But the only one's I can find are beat-up city or Airport fleet vehicles. Might be worth a shot -- but the Phill isn't approved in my State (yet )

The problem with bi fuel systems is that the engine becomes extremely in efficient when running on natural gas. Natural gas has much high octane, lower energy content and takes up move intake volume than gasoline. A pure natural gas engine like the one found on the Civic GX runs much higher compression and completely different engine tuning compared to the gas engine.
The US has much more natural gas than than oil. There are massive deposits in the Gulf of Mexico and the Atlantic coast of Florida. Natural gas could replace oil if we had the economy incentives.

What blows my mind is when they burn off Natural Gas to get at the Oil.

tjts1~ Natural Gas Utility Companies, would be another place to look, too.

That could probably be solved with a little effort, though. Two different fuel maps and a turbocharger or variable valve timing would probably go long ways. I'd like to do a quad-fuel conversion (NG, ethanol, methanol, gasoline) to cover all the bases. Can never be too prepared...

Wyoming has a ton too. Open land there is being pockmarked by thousands of wells. I guess it might be a good short term solution, but it'll only buy time.

Does Dartmouth have one of these?

Is that how you got down for the Rutgers Cycling Event?

Pretty Cool, I hope we get natural gas busses/taxis in ny soon, there is a filling station going up, and the pollution is nasty.
